Carlos Alberto Leumann (1886–1952[1]) was an Argentine poet, teacher, and essayist.

[2] He wrote essays on science and metaphysics, and was the director of the literary supplement in La Nación.

Leumann was born in Santa Fe, Argentina on the 17 of August, 1886, to strict Protestant parents who disliked that he wrote.

During 1916 Leumann was editor-in-chief of La Nota, a literary magazine created and directed by Emin Arslan.

[3] In 1927 he published his first widely read work of fiction in La Nación.
